Asclearly shown in Fig ure 3 thecasings 1 and 5 communicate, and inasmuch as the casings join at right angles the machine has a somewhat exaggerated L-shape.

Doors 6 and 7 at the rear of-the machine permitaccess to-the interior when required. The roller casing 1 is almost completely enclosed when the doors 6 and'7 are shut, this being desirable and necessar to prevent flour, which is always suspenc ed in the atmosphere within the casing to a great-er or less degree,'fro1n escaping to the outside.

For the same purpose, it may be found desirable in practice to provide the casing 5 with a cover or door although the drawings showthe casing to be open so that the mechanism on the inside inay be clearly revealed in the plan view, Fig. 2. The sides and .top of the roller casing 1 provide a foundation upon which the flour bin 8 anddough hopper 9 are mounted. These hoppers are divided by a common partition 10,"

this partition extending; down near the upper pairof-rollers 2 (Fig. 3) where it terminatesin a sharpened or beveled edgell following the. general shape or direction of the nearest roller. The reader. will readily understand that thepartition lOse'parates the dough introduced atthe hopper 9 and the flour contained by the bin 1 i The sides 12 of the dough hopper9 are suitably affixed to. the -interior edges of a pair of guides 13' (Fig. 8) which extend down between the upper pair of rollers 2' (Figs. 3 and 13) for the pur o'se of properly directing the dough blan on its way I through the various rollers and; also for,

limiting the width of the dough blank. It is to be observed that the guides taper downwardly- (Fig. 3) so as to fit between the up er pair of rollers.

ituated at one sideof the roller easing 1 is another casing 15' (Figs. 1 and 2) hereinafter known as the gear box in that it contains or houses the various sprockets chains, etc., for driving the rollers 2, 3 and 4 as well as thepump and conveyor. That side of the casing 1 opposite the gearbox 15 is slotted at 91 along the dough blank passage to permit observation of the progress of the blanks, 1

The gear box is closed by a cover 16 which, as stated before, is shown. removed in'Figure- 1. The various pairsof rollers 2, 3 and 4 are carried by shafts 17 18 and 19 which extend through the sides of the roller-casin 1 and in practice; will be provided with suitable bearings. The various pairs of shafts 17, 18 and 19 are provided with sprockets- 20, 21 and 22 which are so driven that the rollers on opposite sides of the cen- .tral line or dough passageway rotate in the This is accomplished b training a single sprocket chain 23 over an under the various sprockets involved (Fig. 1) use being made ofidlers 2 1 wherever necessary to both properly support the chain and permit of carrying over and under as stated. A large sprocket 25 on one ofthe shafts 19 of the lower pairs of rollers 4 furnishes the driving power for all of the rollers, such power being transmitted by a chain 26 from the sprocket 27 on the main drive shaft 28. This shaft extends out of the gear box 15 at one side and carries a pulley 29 (Fig. 2) to which a driving belt ma be applied. In the event that it is inten ed'to operate the machine b hand the drive pulley 29 will be substitute by a crank, the connection being made inany well-known manner. "The chain a shaft 31.

This shaft carries: an arm 32 (Fig. '3)

which the pump is operated. The-roller is suitably mounted in the yoke 34. carried by the piston rod 35. Thisrod has a piston 36 which operates inside of the cylinder 37 and is for the purpose of discharging air at the blower tube 38 in the flour bin 8. This tube is perforated at 39, and the blast of air carries with it some of the flour in the bin 8 and serves to dust the various pairs of rollers 3 and 4; so that the dough will not stick when rolling the blank.

; The yoke 34 is of an inverted U-shape providing a-convenient mounting for the roller 33 and also for the piston rod 35. A

bracket 39, of inverted L-shape, cooperates 43 between the piston 36 and the lower head.

of the cylinder on the inside limits the move ment of the piston under the influence of the spring 42. In other words, the springs 42 and 4.3 serve to neutralize the position of the piston 36 and keep the roller 33 in that position in which it will be engaged by the arm 32 most effectively- The piston 36 has a cup leather 4 1 which contracts and spreads to respectively let air pass and to compress air veryvmuch on the order of an ordinary bicycle pump.

Air s admitted to the cylinder 37 at the bottom through one or more openings 45.

which periodically engages the roller 33 by Connection ismade between the top of the cylinder and the blower tube 38 through a pipe46 whichincludes a, flexible. section 4.7.

I The pipe 46 and tube 38 might be made continuous, butitis preferable to connect the two by a flexible section and therebymake better connection. j- A coupling 48 joins the pipe 46 with the cage 49 which contains the ball check valve 50. This check valve permits the escape/of air on the upward stroke of the piston 36- and revents fi'our being drawn back from the in 8 on the return stroke of the piston. y L

A cover. 5l necessary for the flour bin 8. This cover is hinged at 52, and must be made to lit the bin all around so that the flour may not be blown out at the topupon the discharge of a blast of air at the tube I 38. It is to be observed (Fig. 3) that the various pairs of rollers are situated at increasing distances apart toward the top of the rollers themselves.

the cage 1. 'lhe'space'betwecn the air 2 is widest,the space between the pair 3 a little narrower and the space between the pair 4 the narrowest of all. The latter space is adjustable,'but' the rollers of the other pair are relatively fixed.

Pairs of guides ,53 and 5% supplement the guides 13 in controlling the movement of the dough from the hopper. 9 to the'place i then are bent inward toward each other and rearward where they terminate in threaded studs 56. These studs are screwed into nuts 57 which are swiveled upon a bar 58 which runs across the back of the machine in a manner similar to the bar upon which the pump piston rod is guided. Upon turning the swivel nuts 57 the shaft 19 of the rearmost roller is moved back and forth in slots 59 in the casing-sides thereby varying the space between the lowermost i -'rollers andregulating the final thickness of the dough blank.

This blank isdischarged upon an inclined shelf 60 (Fig. 3) which extends from' a place between the lowermost rollers 4 toa place immediately above the conveyor belt (31. A scraper .62, working against that roller 4 immediately above the shelf 60 is for the purpose of preventing the dough blank from wrapping around that roller. The conveyor belt 61 is carried by a pair of rollers 63 and 64. The shafts of these rollers are in practice supported in suitable bearings the foremost roller (it being adjustable so that the belt 6l may always be kept under the proper tension.

The belt 61 runs over a platform 90 (Fig. 3), this being necessary to keep the belt from sagging when forming a roll. The shelf 60 carriesa pair of guide cleats 92 (Fig. 14-.) for the purpose of directing the dough blank into the center. of the belt. These are pivoted at 93 for lateral adjustment.

For this purpose there are bolts 65 (Fig. 13) which are threaded at one end and are suitably formed at theopposite end as at 5 6 to receive the ends of the roller shaft. The threaded ends extend through spacing plates 67- and carry wing nuts (38 which, upon beii screwed in the proper direction,

force the iolts 65 forward with the result that the belt 61 is tightened. Both Wing nuts should be operated together so that there may be uniform tension on the belt.

The conveyor belt 61 is provided 'with nu- -me rous' sharp spikes 69 which are arranged in longitudinal and cross rows (Fig. 5) to provide, an ample gripping surface upon which the dough blank is caught upon discharge from the shelf 60 (Fig. 3) and by which the blank is conducted through the casing 5 in the process of making the roll. To this end, co-operation of a presser board 70 is bad. This presser board is loosely supported above thebelt 61 by pairs of studs 71 and .72 which in turn are pendant from bridges 73 and 74: extending across the casing 5. I The ends'of the bridges are bent up and are permanently secured inside of the casing by means of bolts 75. The lugs are all threaded and carry nuts 76 and 77 respectively for the purposes of adjustment. These nuts rest upon the bridges and suspend the presser board 70 in the desired position. The rear end of the presser board is slightly lower than the front end (Fig.

3), in other words, is closer to the belt 61, this being for the purpose of insuring that dough blanks shall be gripped by the buttons 78 beneath the board. The front. end of the board is. supported a little higher from the belt, but the supporting struts -72.

carry lightfsprings 79 which are for the purpose of insuring the proper seaming of the roll upon completion.

1 It is to be observed that the under rear edge of the presser board 70 is slightly rounded or beveled at 80 (Figs. 3 and 12 producing what might be called a throa It is into this throat that the dough blank is introduced upon discharge onto the shelf 60. the initial action of rolling the blank being illustrated in Figure 9. The buttons 78 beneath the presser board oifer resistance to the forward passage of the dough. The conveyor belt 61 in moving forwardly tends to carry the dough forwardly and the result is that the dough blank is rolled over in. the 0 form of a spiral. As the size of the roll the tray. The'traycarries curved-blocks- 94 (Fig. 2)- .which shape the roll'into a increases. the presser board 70 raises, and when the roll finally reaches a place near the discharge end of the casing 5 a plurality of spikes 81 serve to insure the lapping of. 'the end of the blank upon the roll so that it will not come undone when the roll is dis charged upon the tray 82.

' This tray is hinged at 83 so that ing off, and the ledge carries a leg' 85 fur nishing the necessary support. This leg is{ pivoted at 86, and may be slightly turned on the pivot in either of two directions so as to produce a little. variation in the slant of crescent or half moon (Figs. 2 and 11) as the roll moves down upon the tray. 1

The operation is. as follows: Pieces of dough are introduced into the hopper 9 either by hand or otherwise.) The piece of dough enters the. space between the first pair of rollers 2' (Fig.,, 3) where the flattening operation begins, such operation being continued between the pairs of rollers 3 and 4 which last pair discharge the doughblanks shelf at the final and" -"-=oroval-shape.' This shape is a natural con- It is to be observed that three pairs of" upon the inclined desired thickness.

It 'is necessary to gradually reduce the thickness of the dough because it is not advisable to, attemptj' to reduce a piece of dough to a given thick-- ness: in merely one. operation. Use is made of guides-13' '(Fi 8), 5e and 54' (Fig. 4-)r for keeping the ough blank in the central.
